Albedo is not directly dependent on illumination because changing the amount of incoming light proportionally changes the amount of reflected light, except in circumstances where a change in illumination induces a change in the Earth's surface at that location (e.g. through melting of reflective ice). That said, albedo and illumination both vary by latitude. Albedo is highest near the poles and lo… WebSelect from 3500K, 4000K and 5000K at installation with a simple switch located on the driver Direct illumination provides true color over the life of the product Integral LED lens is constructed from PMMA and provides even illumination across the face of the panel Stamped steel LED housing is part of a rigid fixture design Fixture interior painted white … how much is light fall

Anisotropy analysis, such as vertical and horizontal transverse isotropy (VTI/HTI), can be conducted with amplitude versus azimuth (AVAz) reflectivity and azimuthal inversion. WebCorrect Aside from the greenhouse effect, the only factors that affect a planet's average temperature are its reflectivity and distance from the Sun. Since both distance and reflectivity have been measured, the expected temperature can be calculated easily and precisely.

WebJun 3, 2015 · Reflected (or scattered) body waves are the fundamental signals sought in seismic data-acquisition programs. Surface waves travel along the Earth/air interface and do not illuminate geologic targets in the interior of the Earth. Surface waves are noise modes that overlay the desired body-wave reflections.

WebReflectivity is the capacity of an object to reflect solar radiation. It is described as a function of radiation wavelength and is determined by the physical composition of the object.
